Overcurrent protection
element
The device must be operated with a dedicated circuit breaker, as it does not have an
ON/OFF switch of its own.
• The circuit breaker must be easy to reach and labeled accordingly.
• Permitted nominal current of the circuit breaker: 2 A up to maximum 10 A.
Electrical connection → 49
Potential equalization → 55
Terminals Spring-loaded terminals: Suitable for strands and strands with ferrules.

16.6 Performance characteristics
Reference operating
conditions
• Maximum permissible error according to ISO/DIN 11631
• Specifications as per measurement report
• Accuracy information is based on accredited calibration rigs that are traced to
ISO 17025.
To obtain measured errors, use the Applicator sizing tool → 192
Maximum measurement
error
o.r. = of reading
The measurement error depends on a number of factors. A distinction is made between
the measurement error of the measuring device and an additional installation-specific
measurement error that is independent of the measuring device.
